| 摘要： | An asphalt concrete pavement (ACP) overlay over a rigid pavement represents a viable rehabilitation strategy. It can provide good serviceability at an initial construction cost that is substantially less than that of a rigid overlay rehabilitation. In addition, ACP overlays require less construction time, which can reduce user costs during construction. However, it may not be the most economical solution for long-term rehabilitation. Because of their relatively short service life, ACP overlays may require maintenance sooer than rigid overlays. And one of the more critical distresses that effectively determine the life span of the structure is reflection cracking. this report investigates alternative strategies that seek to prevent reflection cracking on ACP overlays. |
